The calculated area of the triangle is 229.0 square units
How to determine the area of the triangle
From the question, we have the following parameters that can be used in our computation:
The triangle
The area of the triangle can be calculated using
Area = 1/2absin(C)
Substitute the known values into the equation
Area = 1/2 * 30 * 18 * sin(122 degrees)
Evaluate
Area = 229.0
Hence, the area of the triangle is 229.0 square units
